These type of prosthetics are used in
dentistry to protect teeth from cracking as well as in certain cosmetic
circumstances. Many different varieties of crown and bridgework exist
which contain various types of metal (ie. non-precious, semi-precious,
precious, and gold). New non-metallic materials are available to create
cosmetic and improved esthetic results. Non-metallic crowns also are an
excellent dental prosthetic treatment option in circumstances when
esthetics is very important (ie. on front teeth for improving the
appearance of one’s smile).
